Best Time To Plant Winter Pansies
Winter flowering pansies are a delightful addition to any garden, providing vibrant colors during the colder months when other flowers are dormant. To ensure the best chance of success, it is recommended to plant winter pansies in September and early October. This timeframe allows the plants to establish their roots and withstand the harsh winter weather ahead.
For those who prefer starting plants from seeds, it’s best to begin the process indoors from June to July. This will give the seeds ample time to germinate and develop into healthy seedlings. Germination typically occurs within 14-21 days, and once the seedlings are big enough, they can be carefully pricked out into individual pots to continue their growth.
Winter pansies can be planted in various settings including:
- Flower beds
- Borders
- Pots
- Window troughs
- Hanging baskets
When planting, it is essential to incorporate a good multi-purpose compost into the soil and add horticultural grit if the soil is heavy. Dig individual holes for each plant and ensure they are planted no more than 10cm apart.
Recommended winter pansy varieties include:
- ‘Matrix Mixed’ with super-sized flowers in various bright colors
- ‘Coolwave Raspberry,’ which is ideal for hanging baskets and pots
These varieties not only provide stunning visual appeal but also have the necessary resilience to survive winter conditions.
Care And Maintenance Of Winter Pansies
Providing proper care and maintenance for winter pansies is crucial for their survival and prolonged blooming period. Regular attention to these delicate flowers will ensure they remain healthy and vibrant throughout the winter months.
To encourage new growth and prevent self-seeding, it is advisable to pinch out finished flower heads from the plants. This process stimulates the development of fresh blooms and keeps the plants looking neat and tidy. Additionally, regular feeding with a balanced fertilizer will supply the pansies with essential nutrients to thrive.
Watering is also critical for winter pansies, even in covered areas. It is necessary to keep the soil moist but avoid overwatering, as excessive moisture can lead to root rot and other fungal diseases. For potted displays of winter pansies, feeding every fortnight is recommended to promote vigorous growth.
Although winter pansies are generally hardy plants, they can be susceptible to downy mildew, a fungal disease that thrives in moist and cool conditions. To prevent this, ensure proper airflow in the garden, avoid overcrowding the plants, and promptly remove any affected foliage.
It is worth noting that winter pansies can also attract slugs and snails. To mitigate these pests, regular checks of the plants and manual removal of any invaders are necessary. Alternatively, organic slug repellents can be used for a more eco-friendly approach.
Pansies Vs. Violas: Similarities And Differences
While pansies and violas may seem similar at first glance, they do have distinct characteristics that set them apart. Both belong to the Violaceae family and are popular choices for many gardeners due to their delightful appearance and versatility.
The primary difference between pansies and violas lies in the size of their flowers. Pansies have larger blooms with heart-shaped petals in various shades, colors, and bicolored combinations. Violas, on the other hand, produce smaller flowers that are often more profuse and abundant.
In terms of seasonal preference, pansies excel in winter gardens, tolerating low temperatures down to single digits Fahrenheit. They are considered hardy annuals that can survive winter and spring in warmer climates. However, when the temperature drops below 25°F, pansies may wilt and turn gray-green.
Violas, on the other hand, thrive in spring gardens and are quick to bloom. They are often seen as a reliable choice for early-season color and are more resilient in cold weather than many other flowering plants. Violas can tolerate frost and even light snow, making them a beloved choice for gardeners eager to bring color to their landscapes as winter fades.

Pansies: Surviving Frost And Winter Weather
One of the key questions gardeners often ask is whether pansies can survive a frost. The answer is yes, winter pansies can endure frost and have an extended growing period, making them an excellent choice for colder climates.
Pansies are known for their cold hardiness, tolerating low temperatures and even thriving in chilly environments. However, it is important to note that pansies planted later in the season are less likely to survive harsh winter weather. By planting them earlier in September or early October, they have sufficient time to establish a strong root system, making it easier for them to withstand the cold.
In areas with particularly severe winters, gardeners can further protect their winter pansies from frost damage by mulching with pine straw. This layer of organic material acts as insulation, preventing the cold air from damaging the plants’ delicate tissues. Furthermore, placing protective covers or cloches over the pansies during extremely cold nights can provide an extra layer of protection against frost.
Pansies: From Blooming In Winter To Surviving Summer Heat
While pansies are best known for their ability to bloom during winter, they also face challenges when the weather gets hot. Pansies do not tolerate excessive heat and humidity well and will cease blooming and become leggy in such conditions.
To combat the summer heat, it is recommended to remove pansies and replace them with summer annuals that thrive in hot weather. The transition to summer flowers ensures a garden that remains visually appealing throughout the warmer months. However, if planted in a shady area, pansies can survive the heat of summer to some extent. Providing partial shade can help retain their beauty and prolong their flowering period.
It is worth noting that pansies are not only valued for their aesthetic appeal but also for their culinary uses. Pansies are edible and can be used in various dishes, such as salads or as garnishes for desserts. However, it is important to ensure that the pansies are grown organically and free from any chemical treatments before using them in cooking.
winter pansies are a simple and reliable way to brighten up gardens during colder months. With proper planting in September or early October, they can withstand frost and thrive in winter conditions. Winter pansies require regular care and maintenance, including pinching out finished flower heads, regular feeding, and watering. While they may struggle in excessive heat and humidity, planting them in shady areas can help them survive the summer months.
